The center is one of hundreds of mail-handling facilities the USPS has identified as in danger of closing. Earlier this year, the agency announced it may close up 3,600 post offices in the nation, nine in Hudson County alone.

According to CNN, Postmaster General Patrick Donahoe explained before a news conference today why the USPS is targeting nearly 250 processing facilities.

"With the dramatic decline in mail volume and the resulting excess capacity, maintaining a vast national infrastructure is no longer realistic," Donahoe said.

Mail volume has declined by more than 43 billion pieces in the past five years and is continuing to decline, according to the USPS.

Upcoming changes will result in a new service standard, resulting in customers receiving mail two to three days after it is mailed, instead of receiving it the next day, the USPS said.
